Addresses a couple of TODOs now that all usages have been
removed and fixes a doc that specifies how the emulator locale
can be set.

We continue to compile external/apache-http into ext.jar. This contains
a few changes apart fom the classes moving around :
- Makefile changes to build docs and api-stubs for now. A future change
will revert these changes and remove these classes from stubs and
docs.
- Hardcode event IDs in legacyerrorstrings to avoid a dependency between
the frameworks and apache. These strings are on their way out and will
never change anyway.
- Remove imports due to {@link} tags and use {@code} instead.
- Remove an accidental(?) dependency on apache commons code that's a
part of apache-http.

The root view of the new uber statusbar should not be focusable.
Based on history, it looks like this was an oversight when this view
was refactored.

This change modifies how global, secure, and system settings are
managed. In particular, we are moving away from the database to
an in-memory model where the settings are persisted asynchronously
to XML.
This simplifies evolution and improves performance, for example,
changing a setting is down from around 400 ms to 10 ms as we do not
hit the disk. The trade off is that we may lose data if the system
dies before persisting the change.
In practice this is not a problem because 1) this is very rare;
2) apps changing a setting use the setting itself to know if it
changed, so next time the app runs (after a reboot that lost data)
the app will be oblivious that data was lost.
When persisting the settings we delay the write a bit to batch
multiple changes. If a change occurs we reschedule the write
but when a maximal delay occurs after the first non-persisted
change we write to disk no matter what. This prevents a malicious
app poking the settings all the time to prevent them being persisted.
The settings are persisted in separate XML files for each type of
setting per user. Specifically, they are in the user's system
directory and the files are named: settings_type_of_settings.xml.
Data migration is performed after the data base is upgraded to its
last version after which the global, system, and secure tables are
dropped.
The global, secure, and system settings now have the same version
and are upgraded as a whole per user to allow migration of settings
between these them. The upgrade steps should be added to the
SettingsProvider.UpgradeController and not in the DatabaseHelper.
Setting states are mapped to an integer key derived from the user
id and the setting type. Therefore, all setting states are in
a lookup table which makes all opertions very fast.
The code is a complete rewrite aiming for improved clarity and
increased maintainability as opposed to using minor optimizations.
Now setting and getting the changed setting takes around 10 ms. We
can optimize later if needed.
Now the code path through the call API and the one through the
content provider APIs end up being the same which fixes bugs where
some enterprise cases were not implemented in the content provider
code path.
Note that we are keeping the call code path as it is a bit faster
than the provider APIs with about 2 ms for setting and getting
a setting. The front-end settings APIs use the call method.
Further, we are restricting apps writing to the system settings.
If the app is targeting API higher than Lollipop MR1 we do not
let them have their settings in the system ones. Otherwise, we
warn that this will become an error. System apps like GMS core
can change anything like the system or shell or root.
Since old apps can add their settings, this can increase the
system memory footprint with no limit. Therefore, we limit the
amount of settings data an app can write to the system settings
before starting to reject new data.
Another problem with the system settings was that an app with a
permission to write there can put invalid values for the settings.
We now have validators for these settings that ensure only valid
values are accepted.
Since apps can put their settings in the system table, when the
app is uninstalled this data is stale in the sytem table without
ever being used. Now we keep the package that last changed the
setting and when the package is removed all settings it touched
that are not in the ones defined in the APIs are dropped.
Keeping in memory settings means that we cannot handle arbitrary
SQL operations, rather the supported operations are on a single
setting by name and all settings (querying). This should not be
a problem in practice but we have to verify it. For that reason,
we log unsupported SQL operations to the event log to do some
crunching and see what if any cases we should additionally support.
There are also tests for the settings provider in this change.

Rewrite the DateUtils' relative time formatting APIs
(getRelativeTimeSpanString, getRelativeDateTimeString) to use ICU ones.
Two APIs that take withPreposition parameter are not changed. Because
(a) ICU doesn't provide functionality to format preposition; (b) They
are not really computing relative time but instead calling
formatDateRange() to get the absolute time/date string.

This is to make sure the East Asian punctuation shared between CJK languages
and Tai Le are rendered from the CJK fonts when no language is specified
for the text, or CJK text is rendered in a non-CJK locale.
Also remove the old comment about 64k glyphs limit.
